Freeze Frame
P0365 CMP Sensor B Circuit No Signal
      

Is DTC P0365 indicated?

     
YES
     
     
     
The failure is duplicated. Go to step 2.
     
NO
     
     
     
Intermittent failure, the system is OK at this time. Check for poor connections or loose terminals at CMP sensor B and the PCM. If the freeze data/on-board snapshot of this DTC is recorded, try to reproduce the failure under the same conditions with the freeze data/on-board snapshot.?
2.
Open wire check (FI MAIN RLY OUT/IGP(MAIN)/IGP(TDC) line):

Open wire check (FI MAIN RLY OUT/IGP(MAIN)/IGP(TDC) line)
?1.
Turn the vehicle to the OFF (LOCK) mode.

?2.
Disconnect the following connector.
CMP sensor B 3P connector

?3.
Turn the vehicle to the ON mode.

?4.
Measure the voltage between test points 1 and 2.
Test condition
Vehicle ON mode
 
CMP sensor B 3P connector: disconnected
Test point 1
CMP sensor B 3P connector No. 1
Test point 2

Test condition
Vehicle ON mode
 
CMP sensor B 3P connector: disconnected
Test point 1
CMP sensor B 3P connector No. 3
Test point 2
Body ground


Is there about 5.0 V?

     
YES
     
     
     
Go to step 4.
     
NO
     
     
     
Go to step 5.
4.
Open wire check (LG line):

Open wire check (LG line)
?1.
Measure the voltage between test points 1 and 2.
Test condition
Vehicle ON mode
 
CMP sensor B 3P connector: disconnected
Test point 1
CMP sensor B 3P connector No. 1
Test point 2
CMP sensor B 3P connector No. 2


Is there battery voltage?

     
YES
     
     
     
The LG wire is OK. Replace CMP sensor B.?
     
NO
     
     
     
Repair an open in the LG wire between CMP sensor B and G101.?
5.
Shorted wire check (TDC line):

Shorted wire check (TDC line)
?1.
Turn the vehicle to the OFF (LOCK) mode.

?2.
Jump the SCS line with the HDS, and wait more than 1 minute.


?3.
Disconnect the following connector.
PCM connector B (51P)

?4.
Check for continuity between test points 1 and 2.
Test condition
Vehicle OFF (LOCK) mode
 
CMP sensor B 3P connector: disconnected
 
PCM connector B (51P): disconnected
Test point 1
PCM connector B (51P) No. 30
Test point 2
Body ground

Is there continuity?

     
YES
     
     
     
Repair a short in the TDC wire between the PCM (B30) and CMP sensor B.?
     
NO
     
     
     
The TDC wire is not shorted. Go to step 6.
6.
Open wire check (TDC line):

Open wire check (TDC line)
?1.
Check for continuity between test points 1 and 2.
Test condition
Vehicle OFF (LOCK) mode
 
CMP sensor B 3P connector: disconnected
 
PCM connector B (51P): disconnected
Test point 1
CMP sensor B 3P connector No. 3
Test point 2
PCM connector B (51P) No. 30


Is there continuity?

     
YES
     
     
     
The TDC wire is OK. Update the PCM if it does not have the latest software, or substitute a known-good PCM, then recheck. If DTC P0365 goes away and the PCM was updated, troubleshooting is complete. If DTC P0365 goes away and the PCM was substituted, replace the original PCM.?
     
NO
     
     
     
Repair an open in the TDC wire between the PCM (B30) and CMP sensor B.?
